Patent number: 8406734Abstract: When an application activation instruction is input, it is decided whether the application is expected to access a high-level protection resource or low-level protection resource (step S31). If the decision is affirmative, display is done to prompt the user to select whether to permit activation of the application (step S32). When the user inputs an activation permission instruction, the application is activated (steps S33 to S36). As a result, only when the user permits an application, which is expected to access a high-level protection resource or low-level protection resource, to access a predetermined resource immediately before its execution, the application is executed. Hence, the basic processing part and application can operate in cooperation with each other while limiting access to various kinds of resources by the application in a reasonable range.Type: GrantFiled: May 14, 2004Date of Patent: March 26, 2013Assignee: Vodafone Group PLCInventors: Osamu Otaka, Mineko Moroto, Norioki Watanabe, Toshihiko Murakami, Satoshi Ogawa, Naomi Nishikata
